Those dang creationists are at it here. They say they want to be doctors and dentists. Fine. But if I find out that my doctor is a creationist, I'm finding a different doctor. If he can be so wrong about something for which there is so much evidence, why should I trust him with my health? 
Creationism is based on fundamentally flawed philosophical presuppositions including the two-model paradigm which holds that either evolution is correct or creationism is. If evolution were to be shown wrong, this doesn't prove creationists correct. The story of Noah, for instance, is one where eight people built in six days a vessel roughly the size of a cruise ship and then amassed a zoological collection to fill said boat the next week. If this doesn't strike you as more than slightly improbable, you should be stripped of any academic qualifications.
Creationism is also based on the presupposition of revelatory and divine-action theism (Intelligent Design loosens this and makes it unnecessary though preferred). This is philosophically unjustifiable, since timebound gods cannot be omniscient and create truly free creatures, and timeless gods cannot act since that would bind them to time.
To accept creationism, you must accept that finite and physical historicity can prove an infinite and non-physical agency. To accept creationism, you must throw out any evidence that suggests the earth might be four billion years old in favour of the presupposition that God put the fossils there to fool us.
You cannot have it both ways: if you throw your chips on the natural world pointing to God, as Christianity did near unanimously back in the centuries before Darwin, then retract your claim and say "Actually, it's all metaphor! Anyone who disagrees is a fundie!". You took your bet, and you lost. The world does not reveal a designer. It reveals cold, merciless indifference and amoral nihilism.
Quick, business opportunity here: register "ismydoctoranidiotcreationist.com" and produce a survey to work out whether your GP is a scientific and intellectual pleb who believes in Noah, the 800-year-old cruise ship owner, and God, who doesn't make anything that evolution can explain (humans, plants, eyes, moral behaviour) but does produce the stuff that evolution apparently can't (bacterial flagella, DNA, mitochondria and the such like). I'd pay a fiver to ensure my doctor isn't better suited for Ken Ham's museum than the practice of medicine.
